Borislav Petkov (AMD)andGreg Kroah-Hartman 44a44b57e8 x86/microcode/AMD: Fix mixed steppings support ...

commit 7ff6edf4fe upstream.

The AMD side of the loader has always claimed to support mixed
steppings. But somewhere along the way, it broke that by assuming that
the cached patch blob is a single one instead of it being one per
*node*.

So turn it into a per-node one so that each node can stash the blob
relevant for it.

  [ NB: Fixes tag is not really the exactly correct one but it is good
    enough. ]
